L67 oil pressure issue.

Best to do that before you bugger anything up even more than it already has been.

If its a new rebuilt engine you will always get fine metal as the rings bed its a giving, problem I say without knowing if he did a proper run in or not, if he used 10w 60 for a run in oil then I would imagine the engine is now farked and needs re-honed again due to lack of lubrication allowing the cylinder walls to heat up to much wearing out the hone to quick and starving engine from lubrication.

Then you have to ask who rebuilt the engine and what was done and replaced?
If the filter was blocked and starving the engine of oil then it be like running a 2 stroke without oil, I say the engine is toast.

Trev, try re-reading the OP (original post). It started good, was quiet and ran fine but turned to **** after. Filter was full off shiny metal bits. Now I'm no expert but this is not from the rings bedding in....

Trevor I rebuilt an engine once and had another rebuilt and there was no filings in the oil either time. I'd say it will be bearings material like mentioned already. The bearings will fail with lack of oil pressure long before the pistons start to seize. I have run an engiine out if oil before and it was knocking quite nicely but it was a long way off locking up.

How does shiny metal get into the oil filter? was the screen removed from pick up? Fine Filing material is in the oil filter as he mentioned when he opened it up along with assembly grease which would off slowed down the oil flow hence the reason the engine is now cactus. Metal on metal not a good thing in any case. Still why 60 weight in a freshly built engine?

Fine metals will pass through the pickup filter screen. If you ever actually took the sump of an engine you would know that...

Do you know the quirks of the Buick V6 oiling system?

Hopefully the OP will come back with some info if/when he tears down the engine. I'd be looking closely at the cam bearings and how they were installed.

X2 yeah, cam bearings were my thought. Given the cam bearings are very hard to fit, without specialised equipment I wonder if they were fitted incorrectly or not replace at all.

Yip did state that!!

Unfortunately if the cam bearings have crapped out the the big ends and maybe mains will be fucked as well now.

Cheers for the info guys. Everything is new and machined on this motor. I pulled the top end down while in the car. One last attempt. Pulled my lifters out and pulled them down to inspect. The lifters themselves have rusted internally. From sitting too long I'm assuming. The contact surfaces have pollished up but it's still full of rust. None of them were stuck on inspection but from the noises I was hearing on initial start up, it makes sense to me that they were seized up at one point.
I'm over my head with this diagnosis stuff but does rust in lifter mean bad?
I tried to take a photo of inside the lifter housing but this was my best effort.
